Once you’re pregnant, you no longer have rights to your own body because another person is occupying it.

Except that a clump of a cells is not a person, so I am not sure how this argument holds.

This reasoning stems from the claim that fathers have an equal share in the property that is the child.

So, does that mean all sperm a man is carrying is also subject to community property rights? Don’t masturbate and destroy shared property, or you can be sued 😂 Sex cells and their less-developed products are not humans and as such not subject to any rights.

By contrast, all those state liabilities - health care, education, social services for children - are “positive rights”. Libertarians assert that these rights are actually an unlawful infringement on one human by another, because they must be paid for out of a communal set of resources.

These kind of services and rights are the reason why people formed civilizations in the first place, that is more organized allocation of resources. They didn’t form civilizations and societies to make some billionaire assholes richer. They don’t maintain social contracts out of the goodness of their hearts or because they’re weak, but because civilization and society provides for them in meaningful and substantial ways. Otherwise it’s slavery, and they have the right to eat the assholes who oppress them.
